I built 2 Kiwi P-30 planes from BMJR kits.  The first one spent a few days in a tree, near the exercise horse track at Danada farms, and needed recovering, after a rainstorm kicked it free. The second flew away at the Bong Recreation Area.  I've made good flights with the Kiwi though.  It has a bigger wing than most P-30's, and mine weighs more than the minimum by a bit, at 71 grams total or 20 grams heavy, so climb is sort of majestic.  

 I used a 6 strand motor, 20 inches long, made up of 1/8 inch wide Tan Super Sport rubber and wound it to 980 turns. The propeller is a Czech 240 mm one.  Flight time was 68 seconds. Wing area is 155 square inches, and wing loading is 2.33 ounces per square foot, and cube loading is 2.25 ounces per cubic foot , so the Kiwi is a floater. The horizontal stabilizer is large, too, at 58 square inches, and may be adding some lift.

 The picture of my Kiwi landing was taken at the Flying Aces Clubs outdoor Champs meet at AMA's Muncie, IN, field, and was posted on Flickr by an AMA photographer.  I hadn't used a dethermalizer fuse, so glide was normal and landing was close to launch.
